Folliculogenesis, Embryo Parameters, and Post-Transfer Recipient Pregnancy Rate in eFSH-Treated Donor Mares
Equine follicle-stimulating hormone (eFSH) treatment increases embryo-recovery rate in donor mares. Recipient pregnancy rates per donor cycle were similar between eFSH-treated mares and non–eFSH-treated progesteroneand estradiol-synchronized donor mares.

متن کاملArtificial insemination and embryo transfer in mares.
Mares can be artificially inseminated with chilled or frozen semen to increase the revenue from their offspring. Embryo transfer can be used to produce more than one foal from a single mare per season. Recent advances in using equine follicle-stimulating hormone to induce superovulation in mares have stimulated research on preserving equine embryos. Equine embryos are usually collected on day 7...
متن کاملTranscervical embryo transfer in performance mares.
Pregnancy was established by transcervical transfer of embryos from performance mares into recipient mares. Estrus was synchronized between donor (n = 17) and recipient (n = 43) mares. After a greater than or equal to 25-mm follicle was detected, donor mares were bred artificially daily until ovulation. Day of ovulation was recorded. Uterine flushes (n = 111) were performed on donor mares 7 day...
متن کاملEmbryo transfer in competition horses: Managing mares and expectations
Embryo transfer (ET) is an accepted and successful technique for obtaining foals from mares without interrupting their competition careers. Recent research, however, suggests that the potential of factors including heat, exercise, repeated embryo flushing and repeated manipulation of the reproductive cycle using exogenous hormones to have a negative impact on fertility may have been underestima...
متن کاملSexual behavior of mares.
The mare is seasonally polyestrus, having an anovulatory period during the short light days of late fall and early winter, and beginning to ovulate as the days become longer during the winter. The complete estrus cycle is typically about 3 weeks, with 5 to 7 days of estrus and approximately 2 weeks of diestrus. When a mare lives within the natural social structure of the horse, i.e. a family ba...
